Rumors have been surrounding the release of Apple's potentially wearable technologies. Signs are hinting at the possible release of the Apple iWatch sometime later this year. The iWatch is thought to combine the functionality of a phone with GPS and health monitoring sensors. Apple's venture into wearable fitness tracking began with Nike+ and the FuelBand, which may have been a platform for the iWatch. Of course, with the product’s release unconfirmed by Apple, the rumors still remain a speculation at best.
